Ben gave

Ben gave BTC 900 to his three children. Everyone received the money in proportion to their age. If their ages are 2yrs, 3yrs, and 4yrs, how much did each get?

Correct answer:

a =  200
b =  300
c =  400

Step-by-step explanation:

$$\begin{gathered} a+b+c=900btc \\ a:b:c=2:3:4 \\ x=\frac{900}{2+3+4}=100 \\ a=2\cdot x=2\cdot 100=200 \end{gathered}$$

$b=3\cdot x=3\cdot 100=300$

$c=4\cdot x=4\cdot 100=400$
